AVAILABLE IN HIGH THERMAL EFFICIENCY TSSOP EXPOSED PAD TSSOP24 TSSOP24 (exposed pad) DIP-24 SO-24 DESCRIPTION The STP16CL596 is a monolithic, low voltage, low current power 16-bit shift register designed for LED panel displays. The STP16CL596 contains a 16-bit serial-in, parallel-out shift register that feeds a 16-bit D-type storage register. In the output stage, sixteen regulated current sources were designed to provide 15-90m A constant current to drive the LEDs. pared with the STPIC6C595, the device provides great flexibility and improved performance in LED panel system design. Table 1: Order Codes Part Number STP16CL596B1R STP16CL596M STP16CL596MTR STP16CL596TTR STP16CL596XTTR Package Trough an external resistor, users can adjust the STP16CL596 output current, controlling in this way the light intensity of LEDs. The STP16CL596 guarantees a 16V output driving capability, allowing users to connect more LEDs in series. The high clock frequency, 25 MHz, also satisfies the system requirement of high volume data transmission. The 3.3V of voltage supply is well useful for applications that interface any micro from 3.3V. pared with a standard TSSOP package, the TSSOP exposed pad increases heat dissipation capability by a 2.5 factor. ments 15 parts per tube 40 parts per tube 1000 parts per reel 2500 parts per reel 2500 parts per reel DIP-24 SO-24 (Tube) SO-24 (Tape & Reel) TSSOP24 (Tape & Reel) TSSOP24 Exposed-Pad (Tape & Reel) July 2005 Rev. 8 1/18 Table 2: Current Accuracy Current accuracy Output Voltage Between bits ≥ 0.7V ± 3% Between ICs ± 10% 15 to 90 m A Output Current Figure 1:...
